A Practical Guide to GPU-Initiated Communication for Molecular Dynamics at Scale

This guide covers GPU-initiated communication techniques using NVSHMEM, which allows GPUs to directly communicate with other GPU memory spaces, leveraging global address space for higher bandwidth and lower latency. The content addresses how traditional CPU-centric approaches like MPI introduce latencies that hinder GPU utilization and scalability in molecular dynamics simulations, presenting GPU kernel-initiated redesigns as a solution.
